Cryptocurrencies are digital assets that have a value, just like a $10 note is a physical token with 10 dollars of value assigned to it.
The difference is that digital currencies are electronic – they only live on the internet. In order for a cryptocurrency to have value, its coin needs to be unique, verifiable and unreplicable. The Bitcoin blockchain was the innovation that made this possible.
Crucial to crypto is the principle of decentralization. There is no single authority or business (such as a bank or government) that controls cryptocurrencies. This idea of sovereignty over your assets and removing reliance on any sort of intermediary is something you’ll hear about a lot.
Decentralization also makes crypto a powerful medium of exchange because it minimizes the costs and processing times of transactions.
Thanks to these innovations, legacy companies like Visa, PayPal and several banks have also begun adopting cryptocurrency and blockchain technologies.
Cryptocurrency uses cryptographic technology to secure individual assets on a database called a “blockchain”. A blockchain records transactions on a network in a way that cannot be altered.
You can think of a blockchain as hundreds of connected computers sharing information with one another. This builds a ledger of data that can be used to validate that each crypto transaction is legitimate and secure.
Some blockchains use a variation of proof-of-work or proof-of-stake consensus algorithms to execute transactions. Proof of work is where the term “Bitcoin miners” comes from.
Miners operate powerful computers that solve complex mathematical problems, which helps secure the blockchain.
Understanding how a crypto’s algorithm works in detail isn’t essential – or easy – but it can help explain movements in price.
The most traded cryptocurrencies are the ones with the highest daily trading volume, meaning they’re bought and sold the most across exchanges. These tend to be large, well-known assets with strong liquidity, making them easier to enter and exit without major price swings.
Commonly most traded cryptocurrencies include:
Why these are traded the most:
What “most traded” actually means:
Trading volume can change daily based on market conditions. Stablecoins like USDT often rank at the top because they’re used to move in and out of trades, not because people are speculating on their price.
Investors can now choose from a number of established and feature-rich crypto exchanges. If you’re just starting out, look for exchanges registered with the Financial Crimes Enforcement Network (FinCEN) that offer US dollar deposits with your preferred payment method.
